I have an issue using Vodafone 3G enabled SIM cards with Cisco HWIC-3G-GSM in a Cisco 1841, i now have 6 HWIC-3G-GSM card that I cannot use at present due to this issue.
If I put a brand new Vodafone sim into a brand new unused Cisco HWIC-3G-GSM card I can establish a connection to the Vodafone 3G network, I obtain an IP address and can access the internet.
If I put a brand new Vodafone sim into a Cisco HWIC-3G-GSM that has previously been used with another providers sim card, in this case T-Mobile or Orange, then I cannot establish a connection to the Vodafone 3G network and do not obtain an IP address.
If I take the same Cisco HWIC-3G-GSM card that failed with a Vodafone sim, it works fine with T-mobile and Orange.
The Vodafone sims that do not work in the Cisco HWIC-3G-GSM do work in a Nokia N95 phone handset.
From what i can see its as if the IOS cannot communicate with the modem in the HWIC-3G-GSM card if its been used previously.
Im using a Cisco 1841 running c1841-advsecurityk9-mz.124-15.T3.bin, here's the relevant parts of the config I am using:

Although profile 1 has the correct APN and chap details i actually wrote this infomation when a T-Moblie sim was in the HWIC-3G-GSM. If I try to write a profile with the Vodafone sim or infact delete the profile the modem does not respond as shown below:

Profile 1 will be deleted
Are you sure? [confirm]
Profile 1 deleted from modem

As mentioned previously i can take the exact same Cisco 1841, same HWIC-3G-GSM replacing the Vodafone sim with a T-Mobile or Orange sim, use same IOS config and the only thing i change is the APN details in the profile to the relevant providers details and everything works fine. I can take the Vodafone sim that does not work in my used HWIC-3G-GSM card and put it into a brand new unused HWIC-3G-GSM card and it will work fine! I have spoken to Vodafone 3rd line and they have confirmed they have no block, bar, or resriction on IMEI on the sims and and the Vodafone sims I have all work in a Nokia N95 handset.
Does anybody know what may be casuing the modem in the HWIC-3G-GSM not to respond?
